• # DataId-Ontology The DBpedia dataid core vocabulary is a meta-data system for detailed descriptions of datasets and their different manifestations. Established vocabularies like DCAT, VoID, Prov-O and FOAF are reused for maximum compatibility to establish a uniform and accepted way to describe and deliver dataset metadata for arbitrary datasets and to put existing standards into practice. In addition dataid can describe the relations of Agents (like persons or organizations) to datasets in regard to their rights and responsibilities.
